摘　　要：高端CT的发展形成三种思路:一是继续增加探测器排数,二是增加球管个数,三是开发探测器新材料。CT能谱成像关键技术是基于新材料(宝石)探测器和瞬时变能高压发生器的基础上实现的,用于成分和性质的鉴别诊断,是CT成像的新模式。The development of advanced CT is divided into three ideas to progress： Firstly to keep on increasing the rows of detectors, Secondly to increase the number of bulbs,thirdly to research and develop new material of detector. The key Spectral Imaging Acquisition Technique of CT applied to discriminate component and character is based on new material of detector such as gemstone and instantaneous high voltage generator to realize the function. Thus it is a new type of CT imaging mode.
